We sell and use the Stop and Go. One of the easiest to use and most efficent ways to seal a hole. None better I feel. Get an old tire and just try to use the BMW kit. Then try the Stop an Go. That should convince you before you are on a trail or a dark road at night cursing what BMW calls a tire repair kit. Don't forget some CO2 cartridges or a nice handy pump for reinflating the tire.

Ditto. I carry both the Stop & Go and the original BMW kit - just in case.

I have used the Stop & Go several times, and have had no trouble. I suspect that either the plugs are installed improperly or there may be some steel belts involved in the reported failures.

Practice using it.

You don't want the first time to be when you are on that dark road at night.

Just before you are going to replace a tire, drill a hole or drive a nail into it (after relieving the pressure so you don't get hurt) and practice plugging it.
